1. Epic storylines and world design.
2. Romantic subplots - <3 Cloud/Aeris and Locke/Celes
3. Engaging battles and game systems
4. Chocobos, airships, summons, crystals, and Cid.
I think that covers everything that I expect in a Final Fantasty game.
Right now, we only have a little bit of 1 and 3, 2 is completely absent, and a dash of 4 (aetheryte crystals).
